Re: upgraded to Cula Dense: wont link

In your linker command I can clearly see that you are mixing 32-bit and 64-bit libs - you will need those to be consistent, for sure.

Edit: You have also indicated that you have installed CUDA 4.1 RC (I say RC because CUDA 4.1 is only available in Release Candidate build presently), but CULA R13 is based against CUDA 4.0. Forward compatibility with future CUDA versions is allowed, but unsupported, so your mileage may vary. Again, with no errors shown I can merely guess. A CUDA 4.1 version of CULA will be released very shortly after CUDA 4.1 is released.
